Over half of septic tanks inspected in Mayo have failed the inspection, according to a new report from the Environmental Protection Agency.
The EPA has today published a review of the 2016 Inspection Plan for Domestic Waste Water Treatment Systems, which shows that, across the country, over half of septic tanks failed local authority inspections, posing a potential health risk to homeowners and their neighbours.
Half of sites with a septic tank and a private drinking water well onsite failed inspection.
In Mayo, 80 inspections were carried out in 2016 - 50 of these septic tanks were non-compliant and only 30 were compliant.
In Roscommon, 31 inspections were carried out, of which 20 failed, and in Co Galway, 95 inspections took place, with 40 failing.
Sligo County Council failed to carry out any of their allocated inspections in 2016.
The report shows that a quarter of septic tanks failed due to owners not removing sludge build-up from their tanks – an issue that can easily be rectified by homeowners, according to the EPA.
The Environmental Protection Agency says the failure by home owners to maintain and operate a septic tank adequately can pose a health & environmental risk through the pollution of private drinking water wells or water courses.
